When children's TV stars go bad: Friday Fiver

We never trusted that Sooty. Sweep was irritating and Soo was a pain in the bum, but we weren't at all surprised to hear that it was in fact the sneaky, whispering bear who had been causing havoc on the set of the show, walloping much-loved veteran entertainer Paul Daniels around the chops with a margherita pizza.

This wasn't the first instance of a popular kids' TV character sullying our childhood memories. They're at it all the time, kicking off our rose-tinted glasses and booting us out of a fuzzy nostalgic slumber. Tube Talk's Friday Fiver looks back at five children's TV stars gone bad:

Rainbow - The Plucking Song"Have you seen Bungle's twanger?" Oh, how we laughed. For anyone who grew up with Geoffrey, Bungle, Zippy and George as friends, it came as something of a shock to discover the cast had filmed a Carry On-esque double-entendre-laden spoof, packed full of more smut than a copy of Nuts magazine.

Cat Deeley drops the F-BombThe face of CD:UK and SMTV Live, the bright young thing of British TV, clean-cut and without a bad bone in her body. Or so we thought. Cat Deeley proved that she had a cheeky side, dropping the F-bomb in Peter Kay's Channel 4 X Factor spoof Britain's Got The Pop Factor. What must poor old Wonkey Donkey think?

Orville turns the air blueWe have not video evidence of it, but there are plenty of personal reports to back up the allegations that cuddly green duck Orville (he wishes he could fly... etc, etc ), who wowed children across the UK in the '80s, is now practicing slightly more adult/blue material with his buddy Keith Harris. Suddenly we have a lot more sympathy for Cuddles the monkey ("I hate that duck"). Well, we've all got to pay the bills, I guess.

Screech - Behind the BellEverybody loved Screech from Saved By The Bell. AC Slater was pretty cool and every boy wanted to be a little bit like Zack, but deep down we all knew that we had more in common with Screech than any of the other Bayside kids. Well, we did until he started spilling the beans on "banging chicks" and hooking up with girls at Disneyland in his tell-all book Behind The Bell. A truly disturbing read, Screech pretty much claimed that the set of the show was one non-stop drug and sex fest. He's also famously starred in a video of the adult variety that we definitely advise you avoid searching for online.

Captain Pugwash and Master Bates?This is one that turned out not to be true, but due to the power of urban myth, many a childhood memory has been ruined. We all watched Captain Pugwash for the hijinks and japes on the Black Pig. However, some cheeky buggers have been determined to persist with the (false) rumours that there were characters called Master Bates, Roger The Cabin Boy and Seaman Staines. For the record, there definitely were not.
